How long is the flowering period of the orchid
The orchid becomes the winter room bright spot with its simple elegant flower posture, the blade sword shape is straight and elegant flower forms the wonderful combination. As a traditional New Year flower, its florescence management directly affects its ornamental value. Understanding the flowering rules and mastering the maintenance know-how can make this fragrance bloom longer in winter. Analysis of Characteristics of Black Orchid Period Natural Blooming Cycle The single-season flowering characteristics of Black Orchid allow it to bloom only once a year, which lasts for about 30 days from November to March of the following year. The best viewing times every day are 10 o'clock in the morning and 7 o'clock in the evening, when the buds are fully stretched and the aroma is the strongest. Environmental impact factors The temperature difference between day and night needs to be maintained at 8-10℃, and the temperature at night should not be lower than 12℃. Humidity is controlled within the range of 60%-70%, and air circulation and scattered light irradiation are key factors in maintaining flowering. The three-element light control plan extends the black orchid period. The flower bud differentiation period (September to October) requires 3 hours of morning light every day. After flowering, it is changed to a scattered light environment with 70% blocking. When using the sunshade net, pay attention to adjust the angle regularly to ensure even light distribution. Water management techniques The principle of "moistening but not wetting" is adopted during the bud stage, and the moisture content of the substrate is maintained at 40%. Use the immersion basin method to supply water, and the water temperature must be consistent with the ambient temperature. Strengthen ventilation for 2 hours after each replenishment. Nutritional supplement strategy Phosphorus and potassium liquid fertilizer (concentration of 0.02%) is applied every 10 days during the bud formation period, and special nutrient for flowers is sprayed on the leaves. Stop fertilizer at full flowering stage and use 0.1% boric acid solution to spray it every week to enhance petal toughness.
Through the coordinated control of the three elements of temperature, light and moisture, and appropriate nutritional supplements, the ink-orchid period can be effectively extended to 45 days. Regularly observe the status of flower stems and cut off residual flowers in time when flowers are found to begin to wilting, which can promote the backflow of nutrients and reserve energy for next year's flowering.
